Would any of the experts in this field be able to identify the "signature" and possibly age? Bought 20 years ago at Leslie Hindman Auction (Chicago) and currently had framed. How to destinguish if Calligraphy or Woodblock? I believe it is Chinese, a native Chinese translated "signature" as E-Mei Mountain Studio? Thanks for the input

Thanks Mark for pointing out the differences in the two seal impressions. Yes there are variances, which could easily be the result of being a wood cut rather than a seal impression, but I think the similarities are so close that they were both carved from impressions of the same seal.

In addition, the configuration of the seal is as close as I can determine from the Chinese websites I searched. Granted the seal impressions were so small as to preclude absolute certainty, but close enough.

To Geo, I am not familiar with the work of Yoshijiro Urushibara, but the seal in Japanese would read: Seizan or Shozan Kamboku. Does this have any relevance to your artist?

Hello, it has been 10 years since you posted this question regarding the beautiful horse block prints so this may be irrelevant now. However, if anyone is interested, I recently found one of the two prints you posted myself and came up with the following from internet search. The artist isYoshijiro Urushibara. He went by more than one name which is why you see different seals on some of his work.
